Apple confirmed at WWDC 2026 that the first iOS 27 public beta will arrive in July. Based on Apple's own announcement and five years of historical release-date data, the public beta is expected to land between mid-July and late-July 2026 — most likely after the third or fourth developer beta has shipped. The first public betas for iOS 16 through iOS 26 all landed between July 11 and July 24. Forbes projects the Release Candidate to arrive in early September — likely around September 9 — with the full public release following on or near Monday, September 14, 2026. Apple confirmed that iOS 27 will support every iPhone currently running iOS 26 — all the way back to the iPhone 11. The centerpiece of iOS 27 is Siri AI, a fundamentally reworked version of Apple's voice assistant that combines personal context, onscreen awareness, and web knowledge. Siri AI gains a dedicated app that lets users revisit previous conversations, pin important chats, and continue threads across all Apple devices via iCloud syncing. It can take actions within apps like Messages, Music, and Reminders.
